First, I would like to thank you for all of your many helpful answers! Thank you!! Basically, I stacked them in the middle of the tank from end to end, leaving some space on the sides, front and back. I created many small caves and spaces due to the crazy shapes of the rocks. I was even able to create a little bridge in the middle with a hole for the fish to swim through. I stacked them pretty securely, again due to the nice shapes, they fit together pretty well. I also added some LR to my 20 gal. refugium, and LR rubble instead of bio balls. I have left the lights off for the first week so far. I will be regulating them on for small amounts of time for the rest of the cycling process.
